Well, not so profound or clever as you might be trying to find... the thing all three have in common is that the layout of their source code is crucial for their meaning. The third program, the maze one, is quite sinister since its layout is not obviously important.
An even better example of this than the second link would be this one. Which is also by Brian Westley, his third consecutive "good god that's amazing!" program... He is my personal favorite contributor, and it's too bad he stopped contributing.
You remind me why I still, deep in my bitter crusty broken heart, love K5. —rusty
